I doubt that's the origin, since "ingegno" means cleverness in italian…

I'm pretty sure the Italian word "ingegno" (like English "ingenious") comes from the same Latin root as "engine": ingenium, meaning "mind or intellect", with "engine" changing its pronunciation and meaning via medieval French.

Well instead of doubting, you can just look it up on wiktionary.
